Which is the alternate exterior angle of ∠ 2?
In the figure, we can observe that ∠1 and ∠7 are alternate exterior angles and ∠2 and ∠8 are alternate exterior angles because: Both lie on the exterior side of the lines; and. They are placed on the opposite sides of the transversal.
What is ⊥ in geometry?
Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines. In Figure , line l ⊥ line m. Figure 2 Perpendicular lines.
What does F X -> mean?
"f" is a function which takes an input, does some kinds of operations, then gives you an output. "f(x)" is the output, and "x" is the input. If "f(x) = x + 3" it's telling you that the output is always 3 more than the input. So if the input is 2, the output is 5 "f(2) = 5".
What does -> mean in maths?
The ⇒ notation means that if the function on the left hand side of the notation is true, then so is the function on the right hand side of the notation. So consider X⇒Y.

What is AB BC AC called?
Right Triangles The longest side of a right triangle is called the hypotenuse and it is the side opposite the right angle. AB (also called c) is the hypotenuse. BC (also called a) and AC(also called b) are legs.
What property is AB BC BC CD?
Geometry Properties and Proofs
| A | B |
|---|---|
| Symmetric Property | If AB + BC = AC then AC = AB + BC |
| Transitive Property | If AB ≅ BC and BC ≅ CD then AB ≅ CD |
| Segment Addition Postulate | If C is between B and D, then BC + CD = BD |
| Angle Addition Postulate | If D is a point in the interior of ∢ABC then m∢ABD + m∢DBC = m∢ABC |

Which angle is the corresponding angle to ∠ A?
Corresponding Angles Formed by Parallel Lines and Transversals
| Angle Type | Definition | Angle Relationships |
|---|---|---|
| Alternate Exterior Angles | The angles formed at the outside or exterior side of the two parallel lines with a transversal. | ∠p = ∠z and ∠q = ∠y |
Which is the alternate angle to ∠ 6?
Alternate angles that lie in the exterior region of both the lines are called alternate exterior angles. In the above image, two pairs of alternate interior angles are ∠3 & ∠5 and ∠4 & ∠6.
What is the alternate exterior angle of ∠ 7?
The term alternate exterior angles is often used when two lines are cut by a third line, a transversal . The Alternate Exterior Angles Theorem states that if k and l are parallel , then the pairs of alternate exterior angles are congruent . That is, ∠1≅∠7 and ∠4≅∠6 .

Property If AB= CD, then CD = AB.
What property states that AB ≅ ba?
Commutative Property For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2. Any time they refer to the Commutative Property, they want you to move stuff around; any time a computation depends on moving stuff around, they want you to say that the computation uses the Commutative Property.
